ryan.erickson_1709311 Feb 15, 2018 5:47 AM (in response to alberto.girolami2_2862441)To clarify, are you measuring the current of just the Sterling-LWB module or the whole system?
I recommend looking at the state of all the IO interfacing to the module. There may be a couple IO in the wrong state that are causing the extra current drain.

Laird(LSR) Support Engineer Feb 26, 2018 9:51 AM (in response to alberto.girolami2_2862441)We are going to set this up and test internally. Our apologies as the question from 2/16 should have been have you measured each IO on the module and confirmed that the state is high or low and if this is the correct state? As mentioned, we're going to try to recreate this internally, please provide all IO pin states so that we can match your setup as closely as possible. Please include any other information that would affect our test/test setup.
Our most common finding for this issue is that one or more pins are in an incorrect state.

mcalhoun Mar 16, 2018 9:55 AM (in response to alberto.girolami2_2862441)1 of 1 people found this helpfulCan you confirm the state of each pin? Do you have them pulled high, pulled low, or left floating (doing nothing with them). Once we know the state of each pin we can replicate your device setup in our lab. Once we have this in our lab we can check the current draw to see if it matches your findings. Then we can proceed with investigating a resolution for the issue.

alberto.girolami2_2862441 Mar 30, 2018 8:30 AM (in response to mcalhoun)Hi mcalhoun,
this is my situation after I call wiced_init() and then wiced_deinit() only:
LOW = 0V
I left the default initializations of the pins made by LAIRD.
Thanks.
